Explanation:

In the digestive system, food molecules are broken down through processes like digestion and absorption. They are chemically and physically broken down into smaller units (e.g., proteins into amino acids, carbohydrates into simple sugars) which are then absorbed into the bloodstream. The original large - complex food molecules thus decrease and essentially 'disappear' in their original form as they are transformed and utilized by the body.

Answer:

they decrease and completely disappear.
